Oxy-fuel technology: An experimental investigations into oil shale combustion under oxy-fuel conditions

- First investigation on oil shale combustion under oxy-fuel conditions.
- A 20 kW Once-Through reactor was used.
- SO2 emissions under oxy-fuel conditions is lower than air-firing by around 30%.
- NOx emission was found to be lower under oxy-fuel conditions than air-firing.
- NOx emission can be reduced efficiently by adopting staged combustion.
